However, the work item\ndump_work may still be running or pending, leading to UAF bugs\nwhen the already freed crash_data is dereferenced again in\nmt7996_mac_dump_work().\n\nThe race condition can occur as follows:\n\nCPU 0 (removal path)               | CPU 1 (workqueue)\nmt7996_pci_remove()                | mt7996_sys_recovery_set()\n mt7996_unregister_device()        |  mt7996_reset()\n  mt7996_coredump_unregister()     |   queue_work()\n   vfree(dev->coredump.crash_data) | mt7996_mac_dump_work()\n                                   |  crash_data-> // UAF\n\nFix this by ensuring dump_work is properly canceled before\nthe crash_data is deallocated.
